Clipping an AC line voltage

I've got a linear step-up transformer (120V AC input) which has an output that under load nominally supplies 230V AC @ 100mA. But with no load it floats to as high as 280 V. I need to switch the load ...

Is this current clamp meter measuring correct according to its specs?

A 24V DC power supply is supplying around 2.4A to a pure resistive load. The input voltage is 230Vrms. So I estimated the rms current drawn from the power network as: P/230 = (24*2.4)/230 = 250mA. ...
